The relationship between horse and rider in eventing is unlike any other sport. While eventing demands the obedience of dressage, the horse must think for itself. While it requires the carefulness of a show jumper, the horse must be equal parts bold. But greater than any trait horses are born with, successful event horses must trust their riders more than they trust their instincts. Cross-country is unique to eventing, and it requires a horse to trust that the lake its rider asks it to leap into is shallow, and that the drop jump into the horizon will have land on the other side.
